Grando GD 1604 i 3200 4 Head Ecosolvent Printer

To dominate the high-volume signage and vehicle wrap market, print service providers require a platform that bridges the gap between blistering production speeds and flawless, high-resolution output. The demand for rapid turnaround times on outdoor banners, backlit displays, and fleet graphics means that downtime is not an option. By integrating a heavy-duty physical chassis with a state-of-the-art multi-head delivery system, print shops can confidently scale their daily square-footage output, secure high-margin commercial contracts, and dramatically lower their total cost of ownership.

Advanced Industrial Performance

The Grando GD 1604 is engineered around a highly stabilized, ultra-heavy industrial chassis designed to eliminate high-frequency vibrations during continuous, high-speed operation. At the core of this structural engineering is a high-precision, CNC-milled aluminum beam paired with a Japanese THK mute linear guide rail. This rigid mechanical foundation ensures that even when the carriage travels at maximum velocity, there is zero lateral deviation, maintaining microscopic dot-placement accuracy across the entire 1.6-meter printable width.

Equipped with four staggered Epson i3200-E1 eco-solvent printheads, the GD 1604 unlocks unprecedented production speeds that easily surpass dual-head alternatives. By staggering the four heads, the print swath is significantly widened per pass, allowing the machine to achieve industrial-grade output speeds exceeding 80 square meters per hour in production mode. This configuration utilizes a dual-motor carriage drive system that delivers smooth, consistent acceleration and deceleration, reducing wear on mechanical components and ensuring round-the-clock reliability for demanding print shops running multi-shift operations.

Core Technology & Media Handling

As a dedicated roll-to-roll eco-solvent platform, the Grando GD 1604 features an advanced media handling system engineered to manage heavy media rolls without skewing or wrinkling. The machine utilizes a synchronized dual-motor take-up and feed system equipped with adjustable tension bars, ensuring consistent media tension from the beginning of the roll to the very end.

To facilitate rapid ink curing at high speeds, the printer is designed with an integrated multi-stage intelligent heating system, consisting of pre-heaters, platform heaters, and post-heaters, complemented by an external infrared drying system and cooling fans. This ensures the eco-solvent ink is perfectly stabilized on the media surface before reaching the take-up reel. Additionally, a multi-section vacuum bed with adjustable suction holding power keeps lightweight or thick media perfectly flat against the printing platter, preventing head strikes and ensuring uniform heat distribution.

Compatible Media & Profitable Applications

The high-density eco-solvent ink chemistry combined with the precision feeding system of the GD 1604 allows print service providers to target a vast array of lucrative indoor and outdoor applications. This system is optimized for high-yield media including:

• Cast & Polymeric Vinyl: Ideal for high-margin vehicle wraps, fleet graphics, and outdoor decals requiring long-term durability and conformability.
• PVC Flex Banners: Perfect for high-volume outdoor billboards, event banners, and promotional signage that demand vibrant colors and weather resistance.
• Backlit Films: Enables the production of high-impact transit advertising, airport lightboxes, and retail displays with deep black densities and rich color saturation.
• Canvas & Fine Art Papers: Expands your portfolio into interior decoration, high-end art reproductions, and textured wall murals.
• One-Way Vision & Window Films: Optimized for retail storefront graphics and architectural glass branding.

RIP Software & Color Management

To harness the full potential of the four Epson i3200 printheads, the Grando GD 1604 offers seamless compatibility with industry-leading RIP software packages, including PhotoPrint (FlexiPrint), Onyx, and MainTop. These software integrations provide print operators with advanced nesting, tiling, and hot-folder automation tools to maximize media utilization and streamline prepress workflows.

The printer operates on a high-efficiency CMYK double-four-color configuration, utilizing Variable Sized Droplet Technology (VSDT). By jetting ink droplets as small as 3.5 picoliters, the system achieves incredibly smooth color gradients, crisp fine text, and photorealistic skin tones. Advanced ICC profiling support allows operators to calibrate color outputs precisely for different media brands, ensuring brand-accurate color matching and minimal ink consumption without sacrificing visual impact.

Maintenance & Operational Safety

Maintaining peak operational efficiency and protecting your capital investment is simplified through the Grando GD 1604’s automated maintenance systems and built-in safety protocols. The machine is engineered to minimize manual intervention and safeguard both the operator and the printheads during daily production cycles.

• Automated Capping & Wiping Station: Features an intelligent, motor-driven capping system that seals the four i3200 printheads airtight when idle, preventing nozzle dehydration and ink clogging.
• Intelligent Ink Scarcity Alarm: Visually and audibly alerts the operator when ink levels are low in the bulk ink supply system, preventing empty lines and printhead dry-firing.
• Anti-Collision Carriage Sensors: Dual physical sensors mounted on both sides of the print carriage immediately halt motion if an obstruction or media wrinkle is detected, protecting the expensive printhead array from physical damage.
• Daily Flushing & Auto-Purging: Programmable cleaning cycles ensure that pigment sedimentation is avoided, maintaining pristine nozzle health with minimal ink wastage.
• Emergency Stop Switches: Strategically positioned physical kill-switches on both ends of the machine allow for immediate operational shutdown in unforeseen circumstances.
